Here is the input file we need to parse −
Welcome to TutorialsPoint. Simply Easy Learning.
IOTester.java
import java.io.File; import java.io.FileFilter; import java.io.IOException; import org.apache.commons.io.comparator.SizeFileComparator; import org.apache.commons.io.filefilter.FileFileFilter; public class IOTester { public static void main(String[] args) { try { usingSizeFileComparator(); } catch(IOException e) { System.out.println(e.getMessage()); } } public static void usingSizeFileComparator() throws IOException { //get the current directory File currentDirectory = new File("."); SizeFileComparator comparator = new SizeFileComparator(); File[] sortedFiles = comparator.sort(currentDirectory.listFiles((FileFilter)FileFileFilter.FILE)); System.out.println("Sorted By Size: "); for(File file:sortedFiles) { System.out.println(file.getName() + ", size(kb) :" + file.length()); } } }
Output
It will print the following result.
Sorted By Size: input.txt, size:124 .project, size:382 .classpath, size:441
